People enrolled in Apple’s Developer Program can now transfer their MobileMe accounts to its hyped, yet-to-be-released iCloud service.

Developers itching to try out Apple’s new cloud service can point their browsers to me.com/move to start the transition, which was first reported by 9to5Mac. Apple will port over a user’s Mail Contacts and Calendar information. Apple says that dashboard widget sync, dock item sync, keychains, signatures, mail account rules, mail smart boxes, and mail preferences will no longer be available after moving to iCloud.

The silver lining: users can continue to use their MobileMe Gallery, iDisk, and iWeb publishing until June 30, 2012 – even if they transition to iCloud.

The general MobileMe-subscribing public cannot use the website to transfer their service just yet. Leslie Horn of PC Magazine reports that non-developers are greeted with a message that says “this account is not eligible” when trying to use me.com/move.

When iCloud is publicly released in the fall users will get 5GB of free storage for documents, backups contacts and calendars. An additional 10GB will cost $20 per year, $40 for 20GB, and $100 for 50GB.

The service will keep a user’s data in sync between Apple devices and PCs that he or she owns. It will certainly be popular among Apple fanboys and users who have multiple iOS devices. Those of you who don’t fit that bill might want to check out Harry McCracken’s cost comparison between iCloud and its competition.
